That's Housewives Cash & Carry on Deptford High Street, not housewives collectively*.
I'm slightly embarrassed to admit that my inner child found this very funny, and demanded that I buy it. My outer adult vetoed another purchase from the same shop - a jar of Hot Shito (and also a jar of Mild Shito) - on the grounds that they were too expensive at £2.29 each.
To be fair, you can probably buy cock-flavoured seasoning in shops the length and breadth of Deptford High Street - I'm sure Housewives does not have exclusive distribution rights on either this or cock soup.
Additionally I am delighted to report that Housewives proved me wrong AGAIN in that I discovered jars of Dijon mustard on its shelves - something I had been convinced I would have to venture to Sainsbury's to buy.
(*Although they are welcome in my house any time, if they are willing to do a bit of dusting.)
